Bill Walton, a two-time NBA champion and member of the basketball Hall of Fame, whose brilliant but injury-riddled career led to a second act as a free-spirited broadcaster who waxed philosophical on the air, died on Monday at the age of 71, the NBA has announced.

Walton, who had a prolonged battle with cancer, was surrounded by his family when he died, the NBA said.

¡°Bill Walton was truly one of a kind,¡± NBA Commissioner Adam Silver said in a statement that recalled his many accomplishments on the court and his ¡°insightful and colorful commentary¡± as a broadcaster. ¡°But what I will remember most about him was his zest for life.¡±
